OF SAME PLACE. I

CHURN-COVER.

SPECIFICATION forming part of Letters Patent No. 361,208, dated April 12, 1887.

Application filed December 27, 1886. Serial No. 229,655. (No model.)

.To all whom t may concern.'

Be it known that I, MoRRis N. GASTLEMAN, a citizen of the United States, residing in the city of Rockford, in the county of Winnebago and State of Illinois, have invented a new and useful Improvement in Ghurns, of which the following is a specification.

rThis invention relates to heads or lids of churns or other vessels, made removable. Its ro object is to provide a removable head for l chnrns or vessels to produce a tight joint, and

having a secure fastening to x itin place in a manner to be readily applied and readily removed.

To this end I have designed and constructed` the lhead represented in the accompanying drawings, which will be hereinafter more fully described.

In the accompanying drawings, Figure 1 is zo an isometrical representation of a removable head Vfor vessels embodying my invention. Fig.` 2 is an isometrical under face view of my l improved removable head. Fig. 3 is an isometrical outer face representation of the annular-ring-head portion of my improved removable head. Fig. 4 is an under face representation of the removable disk portion of the removable head. Fig. 5 is a central sectional representation on the dotted line a ou 3o Fig. l; and Fig. 6 is an enlarged section of the grooved edge portion of the disk-head on the dotted line b, Fig. 4.

In the figures, l represents ametallic annular-ring head having its peripheral edge 3 5 formed to enter the croze or groove as usually formed in the inner face of the vessel near its end. The inner edge of the annular-ring head on its outer face is formed with an uprising bead-formed edge, 2, for a purpose to appear 4o hereinafter. The annular-ring head is also formed with holders 3, rising from its outer face at any proper intervals. The holders 3 rising from the outer face of the annular-ring head are formed on their inner face With aV re- 4 5 cess, 4, khaving the inner face of its outer portion inclined to the plane of the annular-ring head, for a purpose to appear hereinafter.

A metallic disk head, 5, preferably produced from plate material, is formed with an 5o annular groove, 6, on its innerface peripheral edge, and its central portion within the annular groove is produced in crowning form, as

in the figures. A cork or other suitable elastic packing, 7, is placed within the annular groove 6 in the disk-head, and is designed to 55 engage the bead on the outer-face inner edge of the annular-ring head. A metallic spider, 8, of substantially the same diameter as the l disk-head, is pivotal] y connected at its center with the center of the disk-head to turn independently.

The outer annu-lar rim, 9, of the spider engages the outer surface of the grooved portion of the disk-head, and itsperipheral edgeis provided with inclined or wedge-formed projections 10, to enter the recesses 4, formed in the inner face of the holders 3 rising from the annular-ring head. f

Handles 11, rising from the peripheral outer side face of the spider, extend outward and T furnish the means for handling the removable head and to rotate it on its pivotal connection with the disk-head. f

My removable lid is composed, essentially, of three parts, to wit: an annular-ring head to be fixed in the vessel, a removable disk-head to engage theannular ring,vand aspider in connection with the annular-ring head to tix the disk-head in place onthe annular-ring head in a removable manner.

It is evident that slight changes :might be resorted to in the form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I do not wish to limit myself strictly to the construction herein set forth.

In the foregoing I have employed holders of rather small dimensions rising from the annular-ring head, grooved on their. inner face to receive the inclined or wedge-formed pro- 9o jections of the spider; but it is evident that a reversal of these parts, in which the long inoline could be formed onthe annular-ring head and a short projection on the spider to engage the incline on the ring-head, would be within the scope of my invention.

In the manufacture of my improved diskhead from plate material, I prefer to produce it from a single piece, in which instance the annular groove 6, to secure the packing, and also roo its crowning for1n,are produced by striking up, stamping, or pressing. It may, however, he produced in ports, as shown in Fig. 6, in which the central crowning portion, the vertical annular side walls, 12, and the annular cop 13 are formed in separate parts, seemed, grooved, soldered, or otherwise joined at their several meeting points to forni the annular groove 6 to receive the packing.

I claim as my invention-- 1. In combination, an annular metallic ring adapted to be sented within the end of a barrel-like receptacle and provided with upward- ]y-extending holders and with an upwardlyextending annular bead around its inner edge, :t metallic disk-cover having a crowning center, and an annuler groove containing packing adapted to engage the said annular bead,

and a Spider-clamp pivotally secured to the center of the cover and having cams adapted to engage the holders, and a rim adapted to engage the cover over the packing, substantiallly as set forth.

2. In combination, the ring-head adopted to be seated within the head of the receptacle and provided with t cover-receiving iiange and upwardlyextending holders, the metallic disk-cover, with its crown-center and annular packing, and the spider-clamp pivotally secured to the cover at its center :ind provided with the operating-handle, substantially ns set forth.
